/* ══════════════════════════════════════════════════════════════
   MOBILE / TABLET NAV PANEL — FIT ALL SIX ITEMS, NO SCROLL
   Added 2026-07-30.

   Problem: the panel sized nav items in fixed pixels (min-height 58px,
   font-size 1.45rem). Six items plus the CTA came to roughly 550px, which
   overflows the panel on any browser window under about 640px tall. The
   result was a scrollbar and hidden menu items.

   Fix: size the items against viewport height with clamp() so all six always
   fit, and let the CTA absorb leftover space rather than adding fixed height.
   overflow-y:auto is retained purely as a safety net for extreme cases. With
   these clamps it should never engage.

   Nav order is Home, MTWM Framework, Services, Insights, About, Contact.
   Do not reorder.
